Public demos, built with DabyChos Studio

All ten are live at https://demos.dabychos.com · public, no sign-in, invented data · the interfaces are in Spanish

Why these demos exist

In David's words: I build these demos to test DabyChos Studio, a skill that creates apps. You only say what you want the app to be. It researches the apps that already exist in that category and builds one of the best in its field.

Each demo started from an app idea that never shipped. The Studio first reviewed the idea: what was good about it, what was holding it back, and ten concrete improvements. Then it built those improvements into a working demo.

How the demos work

• One page with every screen inside. Every button, menu and card opens its own screen, and the phone's back button works.
• Your own data. Each visitor's data is saved only in their own browser. The first visit loads example data dated today and asks for your name. There is a "reset demo" button.
• Phone, tablet and desktop. Full screen on a phone, a side menu on a tablet, and a phone frame or a desktop layout on a computer.
• Tested in the three browser engines: Safari (WebKit), Chrome (Chromium) and Firefox.
• Locked to its site. The published version only starts at demos.dabychos.com, so a downloaded copy won't run.

1 · APS Pádel

Tournaments with a live bracket, rankings, court bookings without overlaps, and the official padel scoreboard.

What it solves: players in a padel circuit can see when they play, sign up with their partner, follow the bracket and check their ranking, all in one app instead of a group chat.

Key features:

• The whole tournament cycle: sign up with a partner and a category, then the bracket, the results and the ranking points.
• A bracket that advances on its own and rejects impossible scores.
• Rankings by category, with weekly movement and the scoring rules in view.
• Court bookings in half-hour blocks, with no overlaps across clubs.
• A scoreboard with the official count that feeds its result straight into the bracket.
• A home screen that answers "when do I play?".

Demo data: an invented season with 135 players, 10 clubs and 7 tournaments. One live match advances with the clock.
